Record number: 1, Textual support number: 1 CONT
Two methods are commonly used for determining the specific gravities of liquids. One method uses the hydrometer, an instrument that gives a specific gravity reading directly. A second method, called the bottle method, uses a "specific-gravity bottle, "i. e., a flask made to hold a known volume of liquid at a specified temperature(usually 20°C). The bottle is weighed, filled with the liquid whose specific gravity is to be found, and weighed again. The difference in weights is divided by the weight of an equal volume of water to give the specific gravity of the liquid. 3, record 1, English, - pycnometer

Le pycnomètre est essentiellement un flacon de verre surmonté d'une tubulure très étroite portant un trait de repère. Il permet de peser, par différence, la masse du volume bien défini de liquide qu'il peut contenir, la masse du volume d'eau déplacé par un solide immergé dans le flacon rempli d'eau. La masse volumique de l'eau étant bien connue, on en déduit la masse volumique du liquide ou celle du solide que l'on a pris soin de peser séparément. 3, record 1, French, - pycnom%C3%A8tre

Hydrometer methods are based on the same principle as pipette methods [for grain size analysis by means of settling velocity. ] The density of a suspension(and thus its solid matter content) is measured at given intervals after initiation of sedimentation with a hydrometer inserted into the suspension.... The hydrometer method is not very accurate because of errors in reading the hydrometer, displaced particles, disturbance of the sedimentation process by the insertion and removal of the hydrometer, etc. Hence this process is but rarely used in sedimentological investigations. 1, record 2, English, - hydrometer%20method

La méthode [densimétrique] la plus simple, et cependant assez précise, est celle de l'hydromètre. [...] la méthode consiste à suivre la variation de la densité d'une suspension en sédimentation en fonction du temps. La densité est fonction de la concentration en particules solides, le temps est lié à la dimension des grains par la loi de Stokes; on en déduit la distribution de ces dimensions dans le sédiment étudié. 1, record 2, French, - m%C3%A9thode%20de%20l%27hydrom%C3%A8tre
